Description

Everyday eyewear for the hours before sleep. A full-rim rounded square frame with a polycarbonate front and cellulose propionate temples on a metal hinge, in three tints that filter the same and simply look different.

Why the tint matters

Blue light suppresses melatonin, the hormone that tells your body it is time to sleep. Every hour on a screen after dark pushes your sleep window later.

You have probably also seen the headlines saying blue light glasses do nothing. Those studies are real, and they tested clear lenses, the kind that block very little. A randomized trial on properly tinted amber lenses found something different: about thirty minutes more sleep, and less insomnia. Those lenses blocked sixty five percent of blue light.

Lucerna is tinted, and it is built for the evening rather than your whole workday. That is the difference, and it is the only claim we are making.

Choose your tint

Yellow, the lightest tint, for daytime glare and long stretches at a screen
Orange, the everyday choice for evening screen time
Red, the boldest of the three, for when you want the tint to show

All three filter the same amount of blue light. Which one you wear is a matter of taste.

The details

Polycarbonate front and lenses, cellulose propionate temples
A metal hinge rather than moulded plastic
50mm lenses on a 143mm front with 148mm temples, one universal size
Non-prescription lenses, they do not correct vision

Which Tint Should You Start With

The same frame, the same fit and the same filter, so the only thing to choose is the colour you want to look through

The Lightest Tint

Yellow takes the least out, so colours stay close to normal and most people are happy wearing it out of the house

Best for the working day and long stretches at a screen

The Everyday Evening Pair

Orange is the one most people end up wearing most, warm enough to feel like evening without making the room look strange

Best for everything after the sun goes down

The Boldest Look

Red gives the deepest colour shift of the three, so you notice the moment it goes on, and it filters exactly as much blue light as yellow and orange

Best for wearing when you want the tint to be part of the look

The Lens

Deep enough that you can see it working the moment you put them on

The Temples

Enough flex to sit comfortably for hours, even over long sessions

The Frame

Holds its shape, so they look the same in month six as day one

The Hinge

Metal, not plastic, so they open the same way on day three hundred
